The Byrds really started to hit their psychedelic stride on their third album. Roger McGuinn's 12-string freak-outs showed that the band was not content simply to churn out folk sing-alongs. The guitars bend and stretch on songs like "I See You" and "What's Happening?" and "Eight Miles High" just goes for broke. "John Riley" and "Wild Mountain Thyme" are nearly hymn-like.
